Kraken Automotive Stainless Steel Vband clamps are primarily to be used as replacements for our vband clamp kits, however, these will work on MOST other vband systems as well. The clamps are made of 304 stainless steel, the stud and bolt are made of galvanized steel for increased durability over time. We also designed these with an all metal locking nut, far superior to the nylon lock nut when dealing with heat.
